Proper ventilation in the bathroom - and the choice of the main provisions of the exhaust fan

some outbuildings in the house or apartment number of reasons, the most exposed to the process of condensation, so it is advisable to have extra vents.Bathroom - one of these facilities, and inadequate ventilation leads to unpleasant odors and increased humidity, which, in turn, is fraught with subsidence of condensation on the walls, floor and ceiling, which is a breeding ground for fungi and bacteria.Proper ventilation in the bathroom tiles and furniture will keep mold from plaque, will extend the service mirrors will eliminate the causes of odors.


Simple Ways ventilation ↑

simple ventilation in the bathroom by ventilation or by passive exhaust ventilation system can not be fully effective.In multi-storey houses, built over twenty years ago, the ventilation system is gradually polluted and no longer cope with the increas

ing workload.

avoid trouble like musty smell and mold on the walls to help mechanical ventilation in the bathroom, which will remove the moist air out of the bathroom into a common duct and prevent it from returning to the premises.

Inadequate ventilation in the bathroom corrected a number of ways.The first, the most simple, does not require any material and physical costs - an open door, which promotes a constant change of air in the room.This method is justified in cases where the aesthetic component of the dwelling is not decisive.Simply put, if the owners do not care that the bathroom put on public display, this method - perfect.The second method is suitable for those who are already aware of a problem, but not yet ready for its radical solution and is expansion gap under the door.The increase in the door gap of only 2 cm is quite capable to solve the problem of ventilation of a small bathroom.

Selection and sizing of the power exhaust fan ↑

most effective way - is the installation of ventilation in the bathroom in the form of a compact electric fan, which cope with the task, even if unpeeled years of general ventilation system was only a small gap.For this purpose, generally used wall axial fans.When selecting such a device in the first place should pay attention to:

  • Safety, as the fan - electrical appliance and bathroom - a room with high humidity, therefore, protection against ingress of water or steam should be maximum.
  • fan noise, which can irritate the tenants of the apartment.You can set the attenuator, and if that is not enough, then inside the duct to install sound insulation materials;
  • power stretcher must be optimally correlated with the size of the bathroom, and the number of users.If fan power is not enough, install it loses all meaning.

Important!Before you make the ventilation in the bathroom, you need to determine the capacity of the fan.The calculation of the required fan power by the formula 6V or 8V, where V - volume of the bathroom, and 6 and 8 - coefficients corresponding to the number of people who are constantly using bathroom.Factor 8 is used in the calculations, if a bath uses more than 3 people.

ventilation in the bathroom and the toilet can be connected to the light switch, and in this case it will work only when it is really necessary.However, not all are delighted when staying in a closet or bathroom is noisy ventilation.In this situation the best thing to do to extract standalone switch and use it when its work will not interfere with anyone.

basic rules installation of ventilation ↑

and passive, and forced ventilation in the bathroom should be located:

  • at the greatest possible height, preferably directly under the ceiling;
  • as far as possible from the source of fresh air (ideally - on the opposite side), otherwise it will be ensured only local ventilation practically does not affect other parts of the bathroom;
  • fan should be installed away from water sources to avoid short circuits.
Improperly installed ventilation
incorrectly installed ventilation - most of the air mass is out of ventilation and air coming through the door, immediately goes to vent

Typically, installation of ventilation in the bathroom is not associated with additional difficulties, however, the installation of the fanbetter to think in advance.In this case, it is possible to hide the wires inside the walls during the renovation work.If the work has been completed, and the hood has not been established, all the time until the next bathroom renovation will "decorate" the wiring leading to the fan.

What about the ventilation in a wooden house?↑

Ventilation in a private home in the bathroom should be initially included in the project, usually in the bathroom, toilet and kitchen are located hidden ventilation shafts, complete with inlet decorative grilles.If the bathroom in a private house on the ground floor, you can do normal ventilation using natural convection.However, more often in private homes do multiple bathrooms, so the bathroom on the top floor of a house should be set forced ventilation.

of a wooden house is humid and warm air should be removed as quickly as possible, until he had a negative impact on tree

ventilation in the bathroom in a wooden house has serious additional burden due to the nature of the material, so it imposed very differentrequirements.The same applies to the bathrooms, which are fitted with wooden furniture.And wooden walls and furniture, and interior is very exposed to high humidity, so the design of the bathroom in a private wooden house should provide additional ventilation ducts and ventilation installed.It is not recommended for this purpose to use air conditioners, since they strongly dried air, and constant humidity fluctuations can lead to cracking of wood.
